CHURN-DASHER.

SPECIFICATION forming part of Letters Patent No. 360,209, dated March 29, 1887.

Application filed May 11, 1886. Serial No. 201,832. (No model.)

To aZZ whom. it may concern.-

Be it known that I, MARTIN O. DOLSON, of Wichita, in the county of Sedgwick and State of Kansas, have invented new and useful Improvements in Ohurn-Dashers, of which the following is aspecification, reference being had to the annexed drawings, forming a part thereof, in which Figure 1 is aside elevation, partly in section, of my improved churn-dasher. Fig. 2 is a plan view showing the dasher-rod in section.

Similar letters of reference indicate corresponding parts in both figures of the drawings.

The object of my invention is to provide a simple and inexpensive. churn-dasher which will thoroughly agitate the cream and readily separate the butter, and which may be easily taken apart for cleaning.

The invention consists in the peculiar construction and arrangement of parts, as hereinafter fully described, and pointed out in the claims.

To the lower end of the dasher-rod A is secured a ferrule,B,in which is inserted a screw, 0, which is axially in line with the dasher-rod. Upon the screw 0 are placed two screw-wheels, D D, each formed of two bars of wood crossing each other and halved together, and provided with a bushing, a, carrying a flange, b, on the outer surface of the wheel. The arms of each wheel are beveled from diagonally-opposite corners, forming thin blades 0 c. All the blades of each wheel are inclined in the same direction; buttheinclination ofthe blades 0 of the wheel Dis opposite to the inclination of the blades 0' of the wheel D. Constructed and arranged in this way the two wheels will revolve in opposite directions when forced up and down through the cream.

The dasher-rod A is provided with a shoulder, (1, for supporting the wire loop 0, which clamps the plate E to the dasher-rod. The plate E is concave to receive the dasher-rod,

and its ends project equally in opposite directions from the rod. The plate E serves to check the rotation of the cream above the wheels, and causes it to be more thoroughly acted upon by the rotating blades. The turning of the wheels D D near each other also in sures the complete breaking up of the oil globules of the cream and the rapid production of the butter.

When it is desired to clean the dasher, the screw 0 may be withdrawn from the ferrule B and the wheels D D removed and separated, when they may be readily cleansed.

The blades of my improved dasher may be made of wood, metal, or any other suitable material.

I am aware that two dashers arranged upon the lower end of a rod or shaft so as to turn in opposite directions as the said rod or shaft is reciprocated is old, and Itherefore do not claim such invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a churn dasher, the combination, with the dasher-rod A, of the screw-wheels D D,oppositely arranged with respect to each other, the bushing a, having flanges b,and the screw 0, passed through the bushing into the dasherrod, substantially as herein shown and de scribed.

2. The herein-described churn-dasher, consisting of the dasher-rod A, provided with the shoulder d, the screw-wheels D D, oppositely arranged with respect to each other on the lower end of the dasher-rod, the plate E, bent at its center to receive the dasher-rod, and the loop e, for securing the plate to the dasher-rod, substantially as specified.
